Best Wireless Remote?

I just purchased my D7000, tripod and head. I'm looking for a good wireless remote. I went to the local photostore and they tried selling me a $100 Giga T Pro 2.4GHz Wireless Timer Remote. I didn't purchase cause I wanted to ask here first. My main purpose is to use it for taking pictures of family to include myself. I see on Amazon that there are several different cheap $15 options.

Does anyone have any good advice? I don't mind spending $100 but don't want to if it's not needed.
